regulator: cpr3-hmss-regulator: add support for msm8996v3 fuse differences

On MSM8996v1 and v2 chips, the HMSS CPR Turbo corner open-loop
reference voltage is 1.015 V.  On MSM8996v3 chips, this value is
changed to 1.140 V.  Update the driver to support this difference
by identifying the different SoC revisions in device tree using
the compatible property.
